Valve Controller, 0 - 20 mA, 12 V

Features:Multifunction user interface consisting of three pushbuttons and a 3-digit LED display.All parameters are protected against unauthorized changes with a password.Control and regulation of single- or double-coil hydraulic and pneumatic proportional valves used for accurate oil flow regulation, linear soft acceleration and deceleration, modulated output signal, and programmable deadband.Is highly suitable for the joystick regulation of A/B movements. Where changes to A and B need to be selected directly or according to the value of an input signal.During operation, the display shows the present output signal as a % of the I valve.Programmable current or voltage input for standard signals acc. to order schedule, joystick/potentiometer or a special non-programmable input.Digital inputs for external control functions. A pulsating current output prevents the connected valve from sticking.Optional programming of the modulation frequency (PWM) between 8 and 400 Hz.Multiple adjustable parameters such as output currents, ramp times, jump values, chopper frequency, reversal, deadband, and ON/OFF functions.Mounting for a standard 11-pole socket which can be adapted for DIN rail or plate use with PR's 7023 adaptors and 7024 mounting keyings.Input A - 0 - 20 mAOutput 1 - 12 V.
